Nandan Nilekani back to Infosys: Why the clamour?

Is Nandan Nilekani the guy who can restore order back in Infosys after the sudden exit of CEO, Vishal Sikka? The answer to this question lies in the track record that this man has and his ability to get people to work and deliver. He has the trust and faith of all those who have seen him lead the company in the past. What do people have to say about him and why he probably is the man of the hour for a crisis ridden Infosys.
